As is well known, the skin is the largest organ of our body. However, many people still tend to overlook the importance of maintaining a healthy skin barrier. Our skin is basically the barrier between the internal and external worlds of our body. If this barrier is unhealthy, bacteria and other pathogens will penetrate our body and cause serious damage.
Learn more about your skin structure
To take good care of our skin, we first need to understand its structure. Our skin is basically divided into three layers: the epidermis, the dermis, and the subcutaneous layer. In this article, we will focus on the epidermis.
The epidermis can be divided into several layers, one of which is the stratum corneum, also known as the skin barrier, which is the outermost layer of our skin. The structure of this sublayer is very similar to a brick wall, with each skin cell acting like a brick. The "mortar" that binds the "bricks" together is fat, such as ceramides, fatty acids, and cholesterol. These components together are known as natural moisturizing factors, which are very important for the hydration of the stratum corneum.
The key role of the skin barrier
Our skin barrier plays multiple roles in protecting our skin, which are:Protection from a stressful environment
There are many things in daily life that can harm our skin, such as sunlight, pollution, toxins, ultraviolet rays, etc. However, our skin barrier will protect our skin from these external stresses.
Lock in moisture
The skin barrier also regulates the loss of moisture from our skin by retaining the moisture in our body, thus keeping our skin hydrated and radiant.
